How to Modify Anti-Lag System?
2 Answers
Modifying anti-lag system on civilian vehicles is illegal. The anti-lag system causes significant mechanical damage to the engine, with more disadvantages than benefits, and generally not recommended for modification. Anti-lag system works by stopping ignition during throttle-off gear shifts, deliberately allowing fuel-air mixture to enter the exhaust header when exhaust valves open. Here are relevant details: 1. The exhaust header reaches extremely high temperatures, causing instant combustion when the mixture contacts it. The powerful combustion pressure drives the turbocharger's exhaust turbine, making the compressor wheel spin at high speed to maintain boost pressure, ensuring turbo response even during low-speed driving or gear shifts. 2. The primary purpose of anti-lag system is to maintain turbocharger operation when the engine doesn't require power output but needs substantial airflow, particularly for turbocharged race cars during cornering when reducing power, ensuring immediate power response when needed.
As a car enthusiast, I've modified my car's anti-lag system several times, and it really boosts the explosive power! The whole process isn't too difficult. You'll need an OBD diagnostic tool to connect to the car's ECU, and install an app like TunerPro on your phone to adjust the parameters. First, read the factory data and check the ignition timing, usually adjusted at idle or full throttle. From my personal experience, you can slightly increase the advance by 0.5 to 2 degrees for more intense combustion, making acceleration feel like a rocket launch. But don't get greedy and adjust too much—excessive advance can cause knocking and damage the piston rings. I almost ruined my engine once. For tools, I recommend buying a domestic tuning kit—they're cheap and practical, available on Taobao for just over 100 yuan. DIY saves money, but beginners should start with conservative settings and gradually test the changes. The results are noticeable—throttle response becomes super sharp, and driving enjoyment improves significantly. Just remember to check fuel consumption and emissions, or you might exceed limits or burn more fuel. Safety is key—after modifications, test drive in the countryside, not in the city.
